Angra A

The site corresponds to the wreck of a vessel located between the Figueirinha pier and Prainha, which lies at about five meters depth, on a sandy bottom.

The patch of archaeological remains at the site is approximately forty meters long, consisting of a cluster of stones used as ballast that cover much of the wreckage.

It is estimated that the vessel was about thirty-five meters long and eleven meters wide, with some structural wooden pieces still visible, corresponding to the framing and the keel. The latter, of large dimensions, is visible for five meters beyond the ballast patch and measures 25 centimeters in height by 20 centimeters in width. These wooden remains show signs of erosion and the action of "Teredo navalis," a microorganism that feeds on this material.

 

Angra B

The site corresponds to the wreck of a 17th-century Portuguese ship .

In the bay of Angra do Heroísmo, near the Figueirinha quay, which lies at a depth of about five meters.
The archaeological evidence of the site consists of two clusters of wreckage:

• A cluster of large stones used as ballast, measuring fifteen meters long by eleven meters wide.

• A cluster of smaller stones to the north of the first.

This particular distribution suggests that the vessel, after striking the submerged reef, lost its ballast in two phases.

Beneath the ballast stones lie the remains of the ship’s hull timbers, with the keel and pieces of the interior and exterior planking visible. This vessel also features, as a distinctive construction characteristic, a lead lining, indicating 17th-century shipbuilding techniques.
Near the wreck are a small iron artillery piece and small artifacts, such as ceramics and lead cannonballs.

Angra C

The site corresponds to the wreck of a vessel identified in 1996 during the development of survey work for the Archaeological Impact Assessment for the Marina construction project.
It was located at an average depth of seven meters, under a sediment layer more than one meter thick, about 120 meters south of the Alfândega quay. It was characterized by a cohesive set of large wooden elements, along an area with maximum dimensions of about 14.75 meters in length by 6 meters in width, corresponding to a surface of about 90 square meters.

​

In 1998, excavation work took place at the site, with the relocation of the recovered material.

Here, the wooden parts of the vessel are protected under sandbags. It is estimated that the vessel had approximate dimensions of about 13.5 meters in length by 5.5 meters in width, with parts of the frame, keel, and outer planking being recovered. The latter features a double-layer construction with wooden pegs, indicating that it may be a vessel originating from Northern Europe, possibly from the late 17th century.

Various artifacts were also collected, totaling 144 lots, among which a bronze cauldron and a clay pipe stand out.
